Spiralband®NC Case History – Permian Basin
Permian case study on 5 1/2" Drill Pipe
Hardbanding and Inspection Services: Pathfinder Inspections and Field Services
The Operator is responsible for compensating their tubular rental company when drilling tubulars are used and no longer meet premium class. Typically, the tool joints are in premium condition, but the drill pipe has been downgraded due to exterior wear of the tube body. In some cases, tubulars are downgraded in as little as five wells. Even though tubulars are no longer classified as premium, the tube body can meet operational demands if there is no additional body wall loss.
Initially, as a test, the Operator chose Spiralband®NC to be applied to protect 28 lengths of 5.5” O.D. Range II Pipe which had experienced 20-25% loss of the body wall thickness. The testing / drilling program took place in the Permian Basin drilling primary in Sprayberry formation.
Following conclusion of this pilot program, this Operator plans on implementing an additional 265 downgraded assets with Spiralbanding back into the lateral.

Duraband can be easily re-applied over itself with minimal preparation. Duraband NC can also be applied over many other hardbanding products without removal; provided the previous hardband is in good condition. Independent Fearnley Procter NS-1 testing, as well as TH Hill testing has confirmed this. Re-application of Duraband NC costs up to 75% less than competitive products. Test reports and certifications are available upon request.
